Application filed July 14, 1913. Serial No. 779,046.

T0 aZZ fwz om 'it may concern Y Be it lrnown that I, WILLIAM S. HAMM, acitizen of the United States, and resident of Hubbard Woods, county ofCook, and State of Illinois, have invented certainV new and usefulImprovements in Sash-Bolts, of which the following is a specification,and which are illustrated inthe accompanying drawings, forming a partthereof.

The invention relates to bolts for window sashes, and particularly tobolts associated with controlling mechanism secured to a cross-rail ofthe sash at a considerable distance from the sideV thereof.

The object of the invention is to a bolt which, Vwhile housed withintudinal aperture in the provide a longisash rail, may be withdrawntherefrom without removing the sash from its casing. Y p

The invention consists of a flexible bolt associated with any suitablecontrolling mechanism, and is illustrated in the accompanying drawings,in which* Figure 1 is a detail elevation of a sash and its casing, someparts being broken away; Fig. 2 is a detail of thel bolt and one form ofcontrolling mechanism; Fig. 3is a detail of the bolt, two of itssections being shown as separated; and Fig. 4 is a longitudinal section,partly inelevation of the bottom portion of a sash, showing theinvention applied to a metal sash.

The sash casing is represented at 10, and

a horizontal aperture 13, formed in the lower rail of the sash, theforward end of the bolt preferably being inclosed within a bushing 14 ofmetal and being engageable with recesses, as 15, formed in the stile ofthe window casing. Y

The bolt 12 is flexible, this flexibility being provided forein theconstruction as illustrated by forming it of a plurality of sections, as16, 17, 18, as many such sections being employed as may be necessary.The outer end of the bolt is associated with any suitable controllingmechanism, such as the casing 19, adapted to t within a recess in theface of the sash rail and housing a pair of angle levers 20, 21, whichengage a suitable stud, as 22, on the bolt, the levers being controlledby a reciprocable finger-piece 23, provided with a stem24 for engagingthe to include any form free arms ofthe levers. Any suitable spring, as25, is applied for-normally holding the bolt in its advanced position.The aperture 13, within which the bolt is housed, is necessarily quitesmall, being large enough, however, to permit the bolt to play freelytherein without friction. The bolt may be inserted into and removed fromthis aperture through the aperture within which the casing 19 is seated.

Vhen the bolt is made of rigid sections pivotally united, these sectionsshould be of slightly the casing 19, in order that as each section iswithdrawn to the extent of its length the joint uniting it with the nextsection emerges from the aperture 13, and consequently may be exed.

hile I have shown and described a jointed bolt, I do not desire to belimited thereto, as the invention is of sufficient scope of iexiblebolt.

en the sectional bolt is applied to a metal sash, as 26, it is advisableto provide a tube, as 27, withinwhich it may recipro- The tube is shownas having its outer end anchored in the edge wall 28, of the sash andits inner end anchored in a cross plate 29.

I claim as my invention` In combination, a sash, spring-actuatedbolt-controlling,mechanism seated within an aperture in the bottom railof the sash and remote from its end, a flexible bolt attached to thecontrolling mechanism and extending longitudinally through the sash railout of alinement with the mouth of said aperture, and being withdrawabletherefrom through the aperture.

2. In combination,a sash, spring-actuated bolt-controlling mechanismseated within an aperture in the bottomA rail of the sash remote fromits end, a tube leading from the aperture for the controlling mechanismto the end of the rail and being out of alinement with the mouth of saidaperture, a flexible bolt attached to the controlling mechanism andreciprocating within the tube and being withdrawable therefrom throughthe sash aperture.

In combination, a sash bolt comprising a series ofpivotally connectedunits, and a guiding tube within which the several sections of the boltreciprocates in the normal alinement therewith throughwhich the bolt Yaction of the bolt. may be Withdrawn and replaced Without 4c. Incombination, a closure, a bolt comdismounting the closure.
